Answer:
It will take 34.79 years before the solar panel is only able to produce 300 watts of power
Step-by-step explanation:
The equation for the amount of electricity that a solar panel is capable has the following format:
In which Q(t) is the amount after t years, Q(0) is the initial amount and k is the exponential decay constant.
After ten years, a solar panel produces 89% of the electricity that it was able to produce when it was brand new.
This means that . So
So
Initially capable of producing 450 watts of power
This means that
How long will it take before the solar panel is only able to produce 300 watts of power?
This is t for which Q(t) = 300. So
It will take 34.79 years before the solar panel is only able to produce 300 watts of power
We are asked in the problem to find csc (13pi/6). first we can convert the radians angle first to degrees that is equal to 390 degrees. The terminal angle is 30 degrees. csc is the reverse of sin. sin 30 is equal to 1/2, positive since in the first quadrant. hence the answer is 2.
Well since its +1 take that away from 88 and make it 87 then your gonna divide by 9. so 87 divided by 9=29/3 or 9.6inf
so x=9.6 infinite 6
So 1 hour=60 min.,
So 10/1*60/1=600 min. That means 10 hours = 600 min.,
Then add the 39 min. to this equation= 639 min.,
Then you solve for the seconds, 24/1*1/60=0.4,
So 24 seconds is 0.4 (40%) of a minute,
Then it mean that it would take 639.4 minutes for Saturn to make a full rotation.
Hope This helps!!!

Answer:
blank = 0.23
Step-by-step explanation:
to do this you can divide both sides by 100
23/100 is 0.23
blank = 0.23
